LOCOMOTIVE CROSSHEAD GUIDE.

Application filed December 13, 1926. Serial No. 154,590.

My invention relates to certain improve ments in the cross-head guides :tor threecylinder locomotives. y

The object ot the invention is to so construct the guides that they can be readily located in position and cylinder structure of the locomotive and to two cross-ties Which are mounted on the 'trame of the locomotive.

ln the accompanying drawings:

Fig. 1 is a perspective vien7 ot suiqlicient oi a three-cylinder locomotive to illustrate my invention 3 e Fig. 2 is a plan View;

Fig. 3 is a side View; and

Fig. l is a cross-sectional vieiv.

The cylinder structure l has three cylinders, 2a and 3, and three valve-chests l, 4a and 5 which connect with the cylinders and with the steam supply and exhaust passages.

r)The trame 6 ot the locomotive is of any suitable construction, and extending fromr one side member of the trame to the other side member are cross-ties 7 and 8 which overhang the trameand support the guides 9 and 9, respectively, ot the cross-heads 10 which are attached to the piston-rods of the side cylinders 2 and 2a.

The guide 9b for the cross-head 10 which is attached to the piston-rod of the central cylinder 3 is secured by a knee-plate l5 to the central portion ot the cross-tie 7, which is nearest to the cylinders, and has a forward extension ll, which is secured by bolts to a bracket 12 on the head 13b ot the centrai cylinder.

rllie side guides 9 and 9@L are attached to both cross-ties 7 and 8 by bolts as shown, and each toot 71' of the cross-tie 7 is secured by bolts to a bar lei, Which in turn is secured by bolts or other astenings to brackets 12--12a on the heads 18-13a ot the side cylinders.

The three guides are substantially the same in cross-section as shown` in Fig. 4;, and are almost identical in form, With the exception that the central guide has an extension Which is secured directly to the brackets on the cylfirmly secured to the inders. This extension is'omitted in the side `guides as they are connected to the cylinderheads by the bars. l

This construction provides substantial and rigid guides for the several cross-heads of a three-cylinder locomotive.

The bars 14 tie the side guides and bearer to the cylinder-head Without extending the said guides, and enable the side guides to be removed Jfor repairs Without disturbing the cross-tie and cylinder-head.

l. The combination in a three-cylinder locomotive, oi' a main trame; a cylinder structure; three guides; cross-heads mounted to slide on the guides; brackets on the heads ot the cylinders, the central guide being directly attached to the bracket of the head ot the central cylinder; and bars connectingl the side guides to the brackets ot the heads ot the side cylinders.

2. The combination in a three-cylinder locomotive, of a main iframe; cross-ties mounted on the frame, a cylinder structure having` three cylinders; cross-heads for the cylinders; side guides for the side cross-heads, said guides being secured to the ends ot the cross-ties; 'bars connecting the side guides to the cylinder structure; and a central guide secured to one ot said cross-ties and directly connected to the cylinder structure.

3. The combination in a three-cylinder loco1notive,ot a trame; a cylinderstructure having three cylinders and their valve-chests andheads for thecylinders, each head having a bracket; tWo cross-ties mounted on the frame and having over-hanging portions; three guides of substantially the same con- `tour, the side guides being secured to the overlianging portions ot the two cross-ties; bars( connecting` one of said cross-ties to brackets on the heads ot the cylinders, the central guide being attached to one ot said cross-ties and directly attached to a bracket on the head of the central cylinder; and cross-heads adapted tothe guides.
